Normally I would say "In this case it seems to be a problem with your hardware.", but fdisk can see your partitions without problems, so this shouldn't be the case. I would just give it a try, or try a distro with a totally different installer, like Arch, Slackware, Vector, ... .

Okay, i will try Slackware when i get home. hopefully i don't get the same error.

The installer for Slackware (and Slackware itself) is very different from Ubuntu, you will have to partition your disk manually. If you will get an error during that it will hopefully be more helpful than what Ubuntu writes.

If that fail too, would it be possible to add a 2nd hard drive and install ubuntu/slackware, and use the grub to point to the first hard drive(which has windows 7) too. So when it boots, both OS show up?

Yes, that's possible.

Sorry, but this report is lacking the essential information we need, like disk controller and such. Post the output of from a running Linux system.

A machine with AMD 880 chipset, rather comon when it comes to AMD systems and nothing I would expect such difficulties with. Try it with the alternate CD or a distribution with a different installer, like explained above.

Okay, i will try a different cd. i was reading all the other post with the same problem as mine, only 2 were sovled from 30. if the new cd fails i will try to buy a 2nd hard drive and boot from there when i need to. if that fails too, i will stick to linux on a vm. thank you for all the help

Yup, i tried the alternate download and still nothing. i give up! thanks for the help. you can close this thread.

I just thought about one thing I remember sometimes caused problems with older Windows versions. Open the machine and check that the harddisk is connected to the first SATA-port on the motherboard and the CD/DVD-drive on the second (not the other way around).

My computer is only a year and a half old, And the sata ports are in the right place.

hey fishstick1907, have you seen this!?
anyway my laptop is much more than one year old and I can boot from usb, you might want to have a look at the boot sequence in your BIOS.

i dont understand what there asking, unmount all the hard drives? i've tried that too, still the same error. Also, i have 3 partitions in use for windows 7 and i need 3 more for linux (you can have only have 4 partitions at a time in a hard drive). i will stick to using vms for now. thanks anyway.
